• How to query the current free memory in the shared pool

  Hello
  
  Someone please tell me how to check the current uses of shared pool.
  
  Any query/Tip/document would be appreciated?

  If you have found errors ORA-04030 then it is more likely at the PGA instead of the SGA. If you had problems with the shared pool you would probably see shared pool latch wait events and others.

  For the ORA-04030 errors, depending on your operating system, can be solved by adding more memory to the operating system or to reduce the amount of work that is performed.

• How to query the current setting of an element .css?

  I have an element on the stage that I'm changing when running.

  I need to know the current height of the element to be used in a calculation.

  I know how to reset the height, but is it possible, using the script, to determine the current height setting?

  TIA,

  Carolyn

  Any CSS property are accessible as mentioned seano. I would just add sym at the front, since you're on board animate. Just use the correct scope. Then you can use the variable as needed.

  var theHeight = sym.$("element1").height ();

• How to query the data of Contact with multiple fields

  How can I query the data of Contact with multiple fields?

  For example, I'll get contacts which are changed after a point at the specified time and whose country is US. How could I make the chain of research of the SOAP API "Query"?

  And I also want to know how to make a search term for RESTful API for contacts above.

  Any suggestions?

  Thank you.

  Hi Biao,

  The following document describes how query for multiple fields using the SOAP API: request a Contact from several fields.

  And you can search multiple fields using the REST API with the & operator. For example, to search for a Contact by e-mail address and date of creation:

  • " emailAddress ='[email protected]' & converted > = '1369828886'".

  Hope this helps and please let us know if you need more information.

• To get started with Ajax - how to query the db without 'submit' page?

  Hi guys,.

  I'm building a simple "power point presentation" - essentially a CF page that can display a large jpg [slide]) all n seconds, I want the page to query the db to ask whether it is necessary to change the jpg and as appropriate who jpg to see her now. In this way, we can control the presentation by updating the database on the fly.

  So I think I will reach it as follows:

  1. a 'view' page that contains javascript that fires every n seconds code

  2. that js somehow pass 2 variables (GET?) to an action page (ie the user id and authentication var)

  3. the action page will be the query to the db (using the variables passed to step 2)

  4. the action page returns a result (path to jpg for display) which somehow (?) is passed back to the view page

  5. the view swaps page then the jpg is to show for the one passed to him to step 4

  6. Ideally the display page then also pass another variable 2 action page let us know it has received the update and changed the image accordingly

  I'm fine with all the code html and cfm stuff--where I'm stuck is bit of js, I've had a look through google and do not seem to make any progress so if someone could tell me please in the right direction I would be very grateful.

  Excerpts / very welcome advice

  TIA

  Nick

  As well as the very popular jQuery and prototype libraries already mentioned, ColdFusion uses for its wizardary Ajax extJS library and Adobe also provides the Spry library.  Or you can roll you own and upwards, use the function xmlHTTPrequest() JavaScript.

  But I would like to especially underline that all these libraries using the xmlHTTPrequest() feature and that really, you apply to the server, you use just of to do behind the scenes so that the user does not see this JavaScript.  But in regards to the client browser and the server is what are normal requests HTTP and not different responses so if the user clicked on a link or submitting a form.

• How to query the object attribute changed his mind in another display object

  JDeveloper 10.1.3.4
  
  My requirement is I want to be able to query an object (entity based) view on a nonkey attribute where the value I'm looking on can either be in the database on an existing record or only been experienced by updating a different point of view object based on the same entity (and still commit).
  
  When you query the second display of a value object just updated via a different point of view object, the second view object always returns no rows. I thought that the process is:
  
  EntityA
  ViewObjectA based on EntityA
  ViewObjectB based on EntityA
  
  ViewObjectA - line query with the key = 123. update the attribute Y with value 456 (attribute Y in the null database). Feature for EntityA cache, touch 123, attribute is updated with the value 456
  ViewObjectB - line application with attribute = y. wait record in EntityA just updated cache to be returned. Instead, nothing is returned
  
  Here is the code I was using (where RandScheduleEdit and RandScheduleSearch are the same view the entity RandSchedule object-based objects)

    public static void main(String[] args) {
      String        amDef = "test.cache.model.AppModule";
      String        config = "AppModuleLocal";
      ApplicationModule am = Configuration.createRootApplicationModule(amDef,config);
      
      ViewObject rsEdit = am.findViewObject("RandScheduleEdit");
      Key rsKey = new Key(new Object[]{40});
      Row[] rsEditRows = rsEdit.findByKey(rsKey,1);
      Row rsEditRow = rsEditRows[0];    
      rsEditRow.setAttribute("SId", new Number(7827));
      
      ViewObject rsSearch = am.findViewObject("RandScheduleSearch");
      rsSearch.setWhereClause("S_ID = :SId");
      rsSearch.defineNamedWhereClauseParam("SId", null, null);
      rsSearch.setNamedWhereClauseParam("SId",new Number(7827));
      rsSearch.executeQuery();
      Row rsSearchRow = rsSearch.first();
      
      Configuration.releaseRootApplicationModule(am, true);
    }

  Why not rsSearch finds the S_ID = 7827 record? It seems to only be interviewing new records in the database and ignoring the record updated in cache just updated?
  
  Any help much appreciated.
  
  See you soon,.
  Brent

  rsSearch.setNamedWhereClauseParam ("SId", new Number (7827));

  This might help:
  rsSearch.setQueryMode (ViewObject.QUERY_MODE_SCAN_ENTITY_ROWS);

• How to specify the instance in SQL * more command line?

  Hello
  
  I'm learning to Oracle. I currently have 2 instances of database running. I wanted to connect to one of the bodies and used the following command from the command line:
  

  sqlplus system as sysdba/abc123@ocp11gsid
  
  where 1234 is the password for the system user in the ocp11gsys instance.

  When I run the command above, SQL * more ask me the password. I do not understand why he asks me the password because I provided on the command line.
  
  What is the correct command line, so he asks me the password? (without defining the variable ORACLE_SID of environment - basically, I want to know how to specify the user, his password and sid, all in the sqlplus command line, without being prompted to enter the password that I mentioned.)
  
  Thank you for your help,

  John,

  Spot the difference?

  The user name and password must unite. What you are to provide the password with the role where it will not be considered.

  Update
  I missed that part,

  What is the correct command line, so he asks me the password? (without defining the variable ORACLE_SID of environment - basically, I want to know how to specify the user, his password and sid, all in the sqlplus command line, without being prompted to enter the password that I mentioned.)

  The only thing that you can specify is the user name and password. The SID must be defined by you, either explicitly using the export or oraenv command if you are on the local system and do not use the TNS to connect to the instance. If you use the TNS, then an appropriate entry should be there which would connect to the required database.

• How to close the instance of Firefox launched via file/new window without killing all instances of Firefox?

  Before the last update Firefox, running on Ubuntu if it makes a difference, I was able to select close on the file menu (and if memory is also by clicking the x on the last tab) to exit an instance of Firefox open via file new window.

  With the 9.x update this no longer seems to be possible. If I choose the file altogether starting an instance that was launched via the new window, all instances of Firefox away!

  It's embarrassing because I have to leave all the instances that have been launched.

  I tried closing last tab add on, and it allows me to close the last tab content but still leaves the instance running with a blank tab.

  Is there a setting somewhere that I missed to restore the operating mode to exit the additional instances of Firefox without killing all the previous configuration?

  Thank you
  Burt

  Each window must have its own close button (big X in the right corner.)
  But it depends on the 'Theme' that you use in Ubuntu. This large X chould be a round point when you hover over the color changes. It could be on the left instead of the right site.
  This screenshot shows the close the left side, but always an X button.

  CTRL + SHIFT + W closed the window Active.
  CTRL + W closes the current tab.

• How to get the Instance number as one of the fields in a form of the ADF?

  Hello

  We want the Instance # a request to be part of the shape as an output readonly text.

  (I mean the Forum # who appears in the details of the notice of monitoring process, not the activity number):

  

  )

  How can we get the instance # as part of the form?

  Thank you

  Hi Tali,

  The variable pre-defined information "instanceId".  If you use ADF, the human task data control, expand "Process Info" and drag it onto the form.

  I'm curious to know why you want to do it though.  If it's just so that you can report what you see in the list of "Tasks" of your workspace with instances in the list you see when you click on the tab "Monitoring of the process", I think that there is a better way.  The titles in the follow-up process tab do not have by default "No. of instance.  They may instead be given labels if you use 11.1.1.7 or 12 c.  There is a trick to this and it is shown in this blog post: display of labels for Instance in the follow-up process tab.

• How to restrict the instance in the hallway to initiate the user only?

  Hello
  
  In my process, using BPM 11.1.1.6, there are two corridors. The first corridor (SUBMITTER) allows you to instantiate an instance, and after that some tasks in the service, the user moves to the next human task, in the same way. On request, the instance moves to the second hallway (APPROVER). However, if the applicant has not yet presented the second human task (say it just saves) then all other authors of the COMMUNICATION in the same way SUBMIITER, can see his data! Apparently, it's because the instance is given the role of the ISSUER and not attributed to the person of instantiation.
  
  How can we limit the instance be assigned or limited ONLY to the user instancing (during his life in the way of the TRANSMITTER), while other authors of communication may not see his body?
  
  Any help is appreciated.
  Thank you!
  
  PS: are we instantiate the task via API, so we have the flexibility to make an API call if we know what API call will solve this problem. THX.

  One thing you'd want to double check before continuing is to see how the 'creator' predefined variable has the value entered into the human task is defined (not sure what it is about when the API is used).

  Assuming that the 'creator' (or other string variables) is set to userid of the initiator, here are the steps to assign that person to the task in a later human task.

  1. open the human task.
  2. click on the tab "assignment."
  3. click on the icon with the person in it-> click the 'change '.
  4. in the drop-down list, select 'Names and Expressions'-> make sure the 'Value-based' option button is selected-> click on the + icon on the right-> sub select 'Type of Identification', 'User'-> slot 'Type of data' select 'by the term'-> slot 'Value' click on the button «...» ».
  5 expand the 'task'-> scroll down and select "task: creator" (or any string variable that you set for the user ID of the person who created it in the API)-> click "Insert into the Expression"-> click on 'OK'-> 'OK '.

  Hope this helps,

• How to get the instance name of the Clip?

  Hello!

  Is there a way to get the name of the instance of an element of travel when he's on the stage?  In my dress up game, I need to know which elements are on the doll to keep them visible.  My drag and drop feature uses a table and currentTarget:

  var dragArray:Array = [Doll.Drawers.Dress1, Doll.Drawers.Dress2, Doll.Drawers.Dress3, Doll.Drawers.Dress4];
            
            for(var i:int = 0; i < dragArray.length; i++) 
              {
                      dragArray[i].buttonMode = true;
                      dragArray[i].addEventListener(MouseEvent.MOUSE_DOWN, item_onMouseDown);
                      dragArray[i].addEventListener(MouseEvent.MOUSE_UP, item_onMouseUp);
              }
  
  
  function item_onMouseDown(event:MouseEvent):void 
            {
                 var clip:MovieClip = MovieClip(event.currentTarget);
                 clip.startDrag();
            }
    
  function item_onMouseUp(event:MouseEvent):void 
            {
                 var clip:MovieClip = MovieClip(event.currentTarget);
                 clip.stopDrag();
                 if(clip.hitTestObject(Doll.Skins))
                      {
                               //Here's where the problem starts!   ----------------------------------------------  //
                                trace("It's on the doll!");
                      }
            }
  
  

  It can run this code.  However, instead of plotting "It's on the doll!", I would like to transform the currentTarget in its instance name, which should be "Doll.Drawers.Dress1" etc. and to register this name in a table.

  How can I do this?

  I looked into e.target.name, but I keep getting errors...

  Use the name property of the item (if it is the movieclip that you want the name):

  var dragArray:Array = [Doll.Drawers.Dress1, Doll.Drawers.Dress2, Doll.Drawers.Dress3, Doll.Drawers.Dress4];
  
            for(var i:int = 0; i < dragArray.length; i++)
              {
                      dragArray[i].buttonMode = true;
                      dragArray[i].addEventListener(MouseEvent.MOUSE_DOWN, item_onMouseDown);
                      dragArray[i].addEventListener(MouseEvent.MOUSE_UP, item_onMouseUp);
              }
  
  function item_onMouseDown(event:MouseEvent):void
            {
